Whelihan also told Kenney that when it comes to romance, women are mental. They need their brains turned on first. That's not the case with men, she told Kenney.

Whelihan is passionate about her role as a sex educator and said that great sex is something everyone can achieve. She hopes her book, scheduled to be published next year, will help couples of all ages.

Some of the other questions Whelihan asked in her survey included "What are you thinking about during sex?" and "Describe the best sex of your life."

While she won't give away all the answers, she has this tip on how to stimulate desire:

"The No. 1 answer across all age groups was kissing -- sexy, passionate tongue kissing," she said. "Married people don't do that anymore because they're usually quite bitter with each other and they don't like each other too much, but if you could do a one -minute sexy kiss every three days you would totally want more sex with your partner."
